The truck 4 speed will not work in a car. 1st gear will be a granny gear and the shifter comes up in the wrong position.

There are much better heads than the old double hump heads. The aftermarket has really made big gains in cylinder head technology. Plus those old double humps do not have any accessory holes and need harden valve seats to run unleaded fuel.

I would just use a HEI distributor with a msd conversion kit. Those Mallory's are prone to fail, in my experience.

Nothing really special about a 68 truck differential. In most cases it is just a regular 12 bolt with an open carrier (non-LSD). Might be better off to buy a diff already set up for a Nova so it is a bolt-in project.

The cam you choose depends on the rpm range you what the engine to operate in. Then, the rest of the setup will need to match the cam (compression, exhaust, intake, gears, stall, valve springs, ect). Kind of hard to tell if your cam choice is a good one without knowing what you want from your project.
